Malar Fat Pad Flap for the Reconstruction of the Orbit: Case Report

OpenAlex İngilizce

Sebaceous carcinomas are rare malignant tumors of the eyelid.For defects of the orbit, the temporal muscle/fascia and peri-cranial flaps are the preferred options.However, these flaps require extensive dissection, leave obvious scars, and pose a risk of injury to the peripheral nerves.Malar fat flap (MFP) has not been previously described for the reconstruction of the orbital defects.In this paper, we aimed to present a case with an orbital defect after sebaceous carcinoma resection.The MFP was dissected laterally and inferiorly and then rotated superolaterally to fill the defect.The upper and lower eyelids were fixed to the lateral orbital rim to mimic the lateral canthus.No additional scar was created.The magnetic resonance imaging revealed good flap viability after 2 years.The flap was oncologically safe; no recurrence was reported during the 2-year followup period.Pedicled MFP offers a reliable and safe option for minor defects of the orbit.
